TO ALL WIIOM IT MAY GONCERN:

Be it known that I, GEORGE W. SARGENT, of the city, county', and State ot' New York, have invented cer tain novel and useful Improvements in Machinery for Making Nails for Horse-Shoes; and Iihercby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which are letteredto correspond w-ith and form a part ofthe specification.

To enable the public to understand the nature of my invention, and thoso skilled in the mechanic arts to construct and use the same, I will describe it, as follows, to wit:

Figure 1 `is-a perspective drawing of my nail-machine.`

A is the'driving-whcel or power. B is a wooden bar or lever, provided with a. metallic hammer, G, and is secured to the roller U and arm C by means of bolts, or other suitable devices-for such purposes. D is an larm similar to C, and is secured to the transverse roller N, of which it forms a part. E is a wheel, provided with two pins, P P', placed eccentric to its centre.. F F aire horizontal hammers. Y I-I is an adjustable anvil. I is a feed-bar. 1 2 3.4 5, connectingaods. d al are two cams, secured to the main shaft, to operate the horizontal hammers F F and anvil I-I by means of my new mode of connecting the working'parts of my machine,

and operating the sameby the rods 1 2 3, which connect the short levers or arms Gand D and the adjustable bed of the anvil H; also the rods land 5, which are operated upon the eccentric-pins P P Pl by the wheels A and E, to give the desired motion to the cut-oli` bar I. I

In order to reduce the weight of the vertical hammer G, I employ a wooden bar or shank, B, thereby relieving the machine of a part Vof its burden. Yet I do not confine myself to the use of wood alone for such purposes, but use that material which may be thought best. y

By the above arrangement I am enabled to produce two available raps or blows with each hammer to one revolution of the main shaft or wheel A', and thus accomplish more work within the same space of time than 4by any other known arrangement of well-known devices operated by the same or a similar power. Therefore What I claim as novel and useful, and what I wish te secure by Letters Patent of the United States, is-

The levers C and I), connecting-rods 1 2 3 4 5, wheels A and E, with eccentric-pins P P P, arranged to operate the wooden shank and vertical hammer G, adjustable anvil I-I, horizontal hammers F F, and cut-off bar I, substantially in the manner and forA the purpose setl forth, and shown in the drawings.

l In testimony whereof, I hereunto subscribe my name in the p'iesencc of two ',witnesses.

GEORGE W. SARGENT.
